First time using mech mod

[nwhornet]

Even tho those Samsung's say 30T and 40T, I take it don't mean 30 amps and 40 amps

30T is 35A. 40T is 25A & P26A is 30A. All the info is on either Fogstar/18650.co.uk website or Moochs blog & YT videos

First of all these 25r's cost me £12 when I first bought them, and I've already said I'm happy to use bigger batteries if it's safer for me, if I get the 21700's do I still need to up my ohms too

Right easiest way to put it is you have to follow ohm's law to be safe that means staying within the CDR of what ever cell you chose so always set the voltage to 4.2 and calculate your build here

To stay safe, what do you think you should do. All the advice has been given, all info relevant so the choice is yours. As @mattyk2010 has said build higher & use the higher rated cells. Once you're comfortable in your ability to build safely & understand Ohms Law then experiment with different coils/rtas/mods.

I'm guessing if you add an extra wrap, to each pre built coil, you should end up close to this. You 25R isn't up to it. But a 20s will do the job. And it's about the same as your regulated vape power.

I have 5 wraps on these coils, so just add 1 more

Add 1 more and fit it without clipping your leads if possible and check the resistance then half it and if it's within the CDR of your cell then 1 wrap is fine if not take the coil out and add another

So up my ohms and use higher amp batteries

Ok thanks

Yes but not just that learn how to calculate what your doing is safe using a ohm's law calculator

Mooch is god.

Watch some of his videos
https://www.youtube.com/channel/UCePHh3NMvu3rW2LFJeOWo-Q/playlists

Start with the vids in his battery basics playlist
Then his Minding your mahs playlist, watch any that mention mechs in the description.
By then you will have an idea which Minding your mechs and other vids are worth watching.

Yep. Half a wrap on each side.
